Power BI is a Data Visualization and Business Intelligence tool that converts data from
different data sources to interactive dashboards and BI reports. Power BI suite provides
multiple software, connector, and services - Power BI desktop, Power BI service based on
Saas, and mobile Power BI apps available for different platforms. These set of services are
used by business users to consume data and build BI reports.

Storytelling Simplified
Create dynamic Reports &
Dashboards with Power BI. An
array of visualizations options
available. Power BI – helping
you tell a story in a more
presentable way.

DASHBOARD BASICS
A Power BI dashboard is a single page, often called a canvas, that
tells a story through visualizations. Because it is limited to one
page, a well-designed dashboard contains only the highlights of
that story. Readers can view related reports for the details.
Dashboards are a feature of the Power BI service. They're not
available in Power BI Desktop. You can't create dashboards on
mobile devices but you can view and share them there.
The visualizations you see on the dashboard are called tiles.
You pin tiles to a dashboard from reports. If you're new to Power
BI, you can get a good foundation by reading Power BI basic
concepts.
The visualizations on a dashboard come from reports and each
report is based on a dataset. One way to think of a dashboard is
as an entryway to the underlying reports and datasets. Selecting a
visualization takes you to the report (and dataset) that it's based
on.

screen. It shows you the most common data sources first. Then, click the More option
to see a full list of available data sources.

GETTING DATA
• When you click “More..” tab as shown in the above screenshot, you can see a new
navigation window, where on the left side it shows a category of all available data
sources. You also have an option to perform a search at the top.

VISUALIZATIONS
• In Power BI, you can create visualization in two ways. First is by adding from the right
side pane to Report Canvas. By default, it is the table type visualization, which is
selected in Power BI. Another way is to drag the fields from right side bar to the axis
and value axis under Visualization. You can add multiple fields to each axis as per the
requirement.

VISUALIZATIONS
• In Power BI, it is also possible to move your visualization on the reporting canvas by
clicking and then dragging it. You can also switch between different type of charts and
visualizations from the Visualization pane. Power BI attempts to convert your selected
fields to the new visual type as closely as possible.

PUBLISHING &
SHARING

• When you publish a Power BI Desktop file to the Power BI service, the data in the
model and any reports you created in Report view are published to your Power BI
workspace. You’ll see a new dataset with the same name, and any reports in your
Workspace navigator.
• Publishing from Power BI Desktop has the same effect as using Get Data in Power BI
to connect to and upload a Power BI Desktop file.
• To publish a report to the web, you have to navigate to Power BI service → My
Workspace.

• Once you open the report that you want to publish, navigate to the File tab → Publish to Web. Once you select this option,
it opens a new dialog that creates an embed code for this report to include in the website or email.
• Option says: Get a link or embed code that you can include on a public website. You may use publish to web functionality to
share content on a publicly available website. You may not use this functionality to share content internally, which includes
through your email, your internal network, or intranet site. Publish a live version that will remain synchronized with the
source report in Power BI. Any changes you make to the report will immediately be reflected in the published public version.
• When you select - Create Embed code, Power BI prompts that you want to share your data with everyone on the internet.
• The following message is displayed: You are about to create an embed code for this report. Once published, anyone on the
Internet will be able to access the report and the data it contains, and Microsoft may display the report on a public website
or a public gallery.
• Before publishing this report, ensure you have the right to share the data and visualizations publicly. Do not publish
confidential or proprietary information, or an individual's personal data. If in doubt, check your organization's policies before
publishing.
• Note − You can publish the report as a web page and any user with the link can view it. The link can be sent via email or it
can be used as an iframe in a web page.

INTRODUCTION
TO DAX

• Following is an example of DAX formula, which uses a function to calculate a column in
a table:
• Power BI provides an easy way to see the list of all functions. When you start typing
your function in the formula bar, you can see the list of all functions starting with that
alphabet.

• In Power BI, you can create two primary calculations using DAX −
 Calculated columns
 Calculated measures
• When you navigate to the Modeling tab, you can see a New Column option at the top
of the screen. This also opens the formula bar where you can enter DAX formula to
perform the calculation. DAX - Data Analysis Expression is a powerful language used in
Excel to perform calculations. You can also rename the column by changing the
Column text in the formula bar.

• In the following example, we have created a new column: Product Code (Product_C),
which is derived from the last 3 characters of Prod_Id column. Following is the formula
−
• To create a calculated measure, navigate to New Measure tab under Modeling. This
will add a new object under the Fields tab with the name Measure.
Product_C = RIGHT( Sheet1[Prod_Id],3)
